This listing is for a rough slab of Zebra Calcite from Mexico, 100% natural. It can be used for lapidary to make cabochons or as a display specimen.

Zebra Calcite is a striking variety of calcium carbonate distinguished by dramatic, wavy, black, white, cream, and sometimes honey-brown stripes. Also known as "phantom calcite" or "butterfly calcite", this naturally occurring mineral is almost exclusively sourced from mines in Mexico.

The distinct "zebra" pattern forms when calcium-rich water deposits layers of calcite inside fractures and cavities in limestone. Variations in temperature, pressure, and mineral content cause rhythmic banding. The dark stripes get their color from trace mineral inclusions—such as manganese or iron—while the lighter layers are pure calcite.

Details:

• gemstone: Zebra Calcite
• color: black, white, yellow
• dimensions: approx 5 x 4 inches
